Stable 55 Inch Infrared IR Multi Touch Screen Frame Support Windows
7/8/10 Android
Infrared Touch Screen Working Principle:
Infrared Touch Screen is a touch frame which is usually installed
in front of the display screen. The frame is integrated with
printed circuit board which contains a line of IR-LEDs and photo
transistors hidden behind the bezel of the touch frame. Each of
IR-LEDs and photo transistors is set on the opposite sides to
create a grid of invisible infrared light. The bezel shields the
parts from the operation environment while allowing the IR beams to
pass through.
The Infrared Touch Screen controller sequentially pulses LEDs to
create a grid of IR light beams. When a user touches the screen,
enters the grid by a stylus which can interrupt the IR light beams,
the photo transistors from X and Y axes detect the IR light beams
which have been interrupted and transmit exact signals that
identify the X and Y axes coordinates to the host.
Advantages:
